AfterFast, Reliable Home Additions & ADU Across Taft
A home addition or ADU in Taft typically runs $45,000-$130,000 for an addition and $90,000-$220,000 for a detached ADU, with garage conversions landing between $30,000 and $80,000. Those are real numbers we stand behind, and they account for something most out-of-town contractors miss entirely: Taft sits on top of the Midway-Sunset Oil Field, and that changes how we dig, how we pour, and how we permit every project. If you’re planning to add a room or build an ADU in 93268, call us at (877) 610-1318 and we’ll come out, look at your lot, and give you a written line-item estimate you can actually compare.
We’re Barrett & Sons Construction, and we’ve been doing this work since 1998. Tom Barrett’s name is on the truck, his sons run the crews, and when you call, a live person answers. We serve Taft directly, and we know how the oil-field geology under this town affects foundations, excavations, and long-term structural stability. That local knowledge is not optional here. It’s the difference between a smooth job and a surprise bill.
Why Barrett & Sons Construction Is Taft’s Preferred Home Additions & ADU Company
We show up when we say we will. In Taft, that matters more than most places because summer heat regularly tops 105°F, and crews that sleep in past 6 a.m. lose the only workable pour window of the day. Our scheduling accounts for that. We schedule concrete pours and exterior work in early-morning windows when temperatures are still manageable, because pouring a slab in 100-degree afternoon heat is how you get rapid cure, surface cracking, and a foundation that fails within a season. We will not do that to you.
Tom Barrett publishes his name, his address, and his license number. Look it up before you sign anything. Ask anyone on your street, or check with neighbors near the West Side Recreation and Park District. We have been putting our name on work for decades, and we come back when something is not right. That is not a slogan with us. It is the 90-Day Done Right Promise, written on every contract, and one call brings Tom back.
Permits get pulled and inspections get signed on every eligible job in Taft. We know the local building department, we know what the inspector looks for in this town, and we know the oil-field-specific conditions that trigger geotechnical review. The permit inspector works for you, not for me, and that’s why I like him. That’s how Tom puts it, and it’s how we operate.
We also carry the brands homeowners in Taft ask about. For ADU and addition work, that includes Schluter for waterproofing and flooring systems and GAF for any roofing component on the addition. Actual product names you can look up, not mystery materials from the back of a van.
Our Home Additions & ADU Services in Taft
ADU Design & Permitting in Taft
Before we draw a single line, we walk your lot and look at what the oil field underneath it means for your project. In Taft, that’s the starting point for every ADU. We handle the geotechnical review, the permit package, and the site-specific documentation the city needs. You get drawings that reflect what’s actually possible on your lot, not a stock plan from a catalog.
Garage Conversion ADU in Taft
Many Taft garages were built on slab-on-grade foundations poured decades ago, and the Midway-Sunset Oil Field has not been kind to them. Differential settlement is common. We inspect the slab, check for hydrocarbon staining or cracking, and tell you honestly whether that garage can be converted as-is or needs structural work first. If the slab has settled beyond what a conversion can handle, we will tell you that before you spend money on plans.
New Detached ADU in Taft
A new detached ADU means excavation, and excavation in Taft means hitting oil-stained soil more often than not. That’s a reality of building here. We budget for possible soil testing and special disposal from day one, write the allowance into your contract, and issue a change order if the allowance gets exceeded. No surprise at the end. Expect $90,000-$220,000 for a complete detached unit depending on size, finish level, and what the soils investigation returns.
Junior ADU & Interior Conversion in Taft
Converting a garage bay, a bonus room, or an underused section of your existing home into a junior ADU is often the most cost-effective way to add rental income or housing for family in Taft. These projects live inside your existing footprint, which means less excavation and less oil-field risk. But on a 1940s or 1950s worker cottage, the existing walls often hide exactly what we found on a recent job near the West Side Recreation and Park District: cloth-wrapped wiring, sagged ceiling joists, and cracked sill-plate sealant. We document it, price it, and get your approval in writing before we touch anything.

Trusted Brands We Service in Taft
When we build an addition or ADU in Taft, we install materials that hold up to San Joaquin Valley heat and the low humidity that destroys cheap sealants inside one summer. We use Schluter waterproofing systems for showers and wet areas, GAF roofing products on any new rooflines, and we specify products from brands homeowners can verify. If you already have a brand in mind for your project, tell us, and we will price it honestly. We do not swap in something cheaper without a written change order in your hand first.
Common Home Additions & ADU Problems We See in Taft Homes
- Hydrocarbon-saturated soil during excavation. When we dig footing trenches for an addition or ADU in Taft, we routinely encounter oil-stained soils that require testing and special disposal. Out-of-town builders get blindsided by the cost and the permitting delays. We plan for it from the first site visit.
- Original cloth-wrapped wiring behind walls. Homes built for oil field workers in the 1940s through 1960s often still carry wiring that predates modern code. Once we open a wall, the permit requires upgrades, and that is a cost you need to see on paper before work proceeds. We write it into a change order and get your signature.
- Undersized framing and deferred maintenance. Boom-and-bust oil cycles meant some Taft homes got repairs skipped for years at a time. We routinely find sagged ceiling joists and load paths that cannot support a second story without reinforcement. We confirm what’s there before we promise what’s possible.
- Slab settlement from oil-field subsidence. The ground under parts of Taft has shifted over decades of petroleum extraction. An existing slab may look fine and still be out of level enough to matter for a new addition. We check with a leveling survey, not a guess.

FAQs - Home Additions & ADU in Taft
Yes, in most cases a geotechnical report is required for an ADU foundation in Taft because the city sits directly over the Midway-Sunset Oil Field, and the permitting authority wants to know what’s under the slab before you pour it. We coordinate the testing, submit the report with your permit package, and price any required soil mitigation in your contract before we break ground. Call (877) 610-1318 to start this process, and we’ll walk you through exactly what your lot needs.
You get a written change order before any new work starts. That’s what happens. We document what we find, price the code-required upgrades, and get your signed approval before we touch another stud. We found cloth-wrapped wiring, sagged joists, and failed waterproofing on a 1950s worker cottage near the West Side Recreation and Park District, and the homeowner knew the exact cost of every fix before we made the first cut. No surprise invoice at final inspection. Ever.
Because Taft summer temperatures regularly exceed 105°F, and pouring concrete in that heat causes rapid cure, surface checking, and a slab that can crack within weeks. We schedule pours in early-morning windows, typically starting before 7 a.m., so the concrete sets before the worst heat arrives. It’s a simple scheduling decision that protects your foundation for decades.
Sometimes yes, sometimes no, and you want an honest answer before you spend money on plans. We inspect the slab, measure the settlement, and check for the hydrocarbon staining that’s common in Taft garages. If the slab can support a conversion with minor leveling and reinforcement, we will tell you and price it. If it cannot, we will tell you that too, and we’ll discuss what a replacement foundation costs. Call (877) 610-1318 for a free slab assessment and we’ll give you the straight answer.
We pull the permits, schedule the inspections, and stand behind every one of them. On an older Taft home, opening walls means the inspector will require electrical, structural, and possibly seismic upgrades to current code, and those requirements get priced into your contract before work begins. You will never be asked to pay for a code upgrade that wasn’t already in writing. The permit inspector works for you, not for me, and that’s exactly how we like it.
